Specification of Letters Patent.

Patented June 27, 1911.

.Application led November 3G, 1908. Serial No. 465,218.

To all whom 'it may concern:

Be it known that I, JOSEPH STUBBERs, a citizen of the United States,residing at Covington, in the county of Kenton and State of Kentucky,have invented certain new and useful Improvements in Service- Pipes forLighting Systems, of which the following is a specification.

My invention relates to an improved construction in or attachment to theburner pipe of a hydro-carbon incandescent lighting system.

The object of the invention is to prevent the condensed vapors fromgaining access into the burner proper.

Another object of the invention is to trap these combustible uids ofcondensation before they enter the burner and preferably in a positionlocated within the heating zone of the flame, so that the fluid willevaporate 0E in a harmless manne-r.

The invention is shown and has particular utility in connection withincandescent mantle burners of the inverted type. In this type thefluids of condensation more readily find their way intol the burner andfall therefrom into the flame causing an undesirable re hazard. Inhydro-carbon lighting systems condensation of vapors in the horizontalpipes is apt to occur, and the flow of the gases carries the fluid intothe burner. By my invention I interpose a fluid trap in the service pipeto the burner in such a way as to catch these fluids and hold them whilethe gas passes on to the burner.

The features of the invention are more fully set forth in thedescription of the accompanying drawing, forming a part of thisspecification, in which Figure 1 is a central vertical section of mytrap for fluids of condensation in connection with burner. Fig. 2 is aside elevation of the same. Fig. 8 is a top plan view.

1 is the inverted burner tube and 2 the burner from which anincandescent mantle is suspended. Upon the upper end thereof is secureda sleeve or chamber 3 of larger diameter than the burner tube with theupper end of the burner tube projecting through the base portion 4 ofthis chamber, so as to extend above the same. 5 represents a valve ofthe disk type for sealing this open upper end of the burner tube. It isconnected to a rod 6, which .is raised and lowered by means of the levermechanism.

This valve disk 5 is movable axially over the mouth of the burner tubeand forms a sort of a hood, which condensation from falling into theburner tube. This sleeve forms a continuous channel with the burnertube, being in vertical registration therewith, but of larger diameter,so that any condensation occurring within this sleeve will deposit uponthe inside walls thereof and flow down upon the floor below the valve,being thus prevented from finding entrance into the burner tube. Theupper portion of the chamber is in connection with a supply pipe 8. Thelever mechanism for operating the valve 5 comprises an arm 7 connectedwith the rod 6 at one end, and at its opposite end to the actuating rod9. The rod 9 is bent at one end forming a projection l0, adapted to movebetween the stop lugs 11, projecting from the shell of the chamber 3.

12 represents a spring controlled plunger, bearing against rod 9 tofrictionally maintainthe valve in any adjusted position.

13 represents a valve actuating bar secured to rod 9.

While the valve 5 is shown in the chamber 3, this is not of the essenceof the invention. In its broader aspect the element 3 is a condensationchamber or a fluid trap interposed between the service pipe and theburner, which has the function of catching the fluids of condensation insuch way as to prevent their access into the burner tube withoutinterfering with the flow of gas, and this trap is preferably interposedin position to be located within the heating zone of the flame, so thatthe trapped fluids may harmlessly evaporate.

Having described my invention, I claim 1. In a burner for pre-admixedhydro carbon vapor and air, a vertically alined and slightly separatedservice pipe and burnertube, means for attaching a mantle directly tothe lower end of the burner tube, a shell inclosing the adjacent ends ofsaid pipe and tube, said tube projecting upwardly into the shell,whereby the shell is in the immediate proximity of the mantle, a valvewithin said shell for opening and closing and screening the open end ofthe burner tube, and means exterior of said shell for operating saidvalve.

2. In a burner for pre-admixed hydro carbon vapor and air, a verticallyalined and revents any liquid slightly separated service pipe and burnertube, means for attaching a mantle directly to the lower end of theburner tube, a shell inclosing the adjacent ends of said pipe and tube,said tube projecting upwardly into the shell, whereby the shell is inthe immediate proximity of the mantle, an axially movable valve disk inthe shell for the mouth of the burner tube, forming a hood to pre- Ventliquid condensation falling into the 10 burner tube, and means projectedthrough the shell for operating the Valve.

In testimony whereof, I have hereunto set my hand.
